Atari announces Nemesis Confrontation, a special event for Champions Online, Cryptic's superhero MMORPG that will kick off on November 24. The event will overlap with a free weekend that will run from November 26-30 allowing a free sample of the game, and they are also planning a developer chat tomorrow where the event will be one of the topics at hand. You can post questions to this forum thread and connect to the chat through this link tomorrow at 7:00 pm EST. This page has details on the event, and here's a bit from the announcement:

"We wanted to take our unique Nemesis System to the next level and do something really awesome with it," said Bill Roper, Executive Producer of Champions Online. "So we asked ourselves, what if your Nemesis could band together with your buddy's Nemesis to take you on? Epic."

Players will learn that their uniquely handcrafted Nemeses are trying to create a rift into another dimension in a plot to take over the Champions Universe. To save the world, a band of superheroes will need to defeat their ultimate enemies, as well as a host of dangerous alien gladiators and prison guards in an all new environment. The Nemesis Confrontation event will also launch alongside a free weekend of play that takes place between November 26 and November 30.
